A developer shares deep technical insights from optimizing an Elixir-based Postgres connection pooler, revealing performance optimization techniques including flame graphs, telemetry overhead, ETS tables, and GenServer limitations. The article provides practical lessons learned from pushing Elixir performance to handle hundreds of thousands of operations per second. These optimizations are valuable for developers working on high-performance Elixir applications.
Background
Elixir is a functional programming language built on the BEAM VM, known for its concurrency capabilities and used in high-performance distributed systems. Performance optimization in Elixir often involves understanding BEAM VM internals and Erlang/OTP patterns.
